I just get a http error status and a blank page. Are they saying that HN sent too many people to their site? If so how many is too many for them? HN active user base is not that big so I would assume the issue is too many AI bots scraping and following links from HN which also means the AI bots are ignoring rel="nofollow" if that is the case.

So many posts today referring to articles on the site brought it down. I suppose we should keep this in mind when posting. I assume it wasn't intentional. :-)
